A positioning system for an optical system can include a support frame and a flexure arrangement. The flexure arrangement can be configured to secure an optical-system component relative to a support frame, with the optical-system component in a first orientation. The flexure arrangement can be configured to resiliently deform, upon application of a transient stress to the optical system, to move the optical-system component relative to the support frame along at least one degree of freedom. The flexure arrangement can be configured to return the optical-system component to the first orientation upon removal of the transient stress.

A measurement apparatus for mounting within an enclosure of a machine is described. The apparatus includes a measurement device and a protection means for protecting the measurement device from contaminants present within the machine enclosure. The protection means is switchable between at least a first mode that protects the measurement device from contaminants and a second mode that provides less protection of the measurement device from contaminants than the first mode. A contaminant sensor is used for sensing contamination within the machine enclosure and thereby determining when the protection means can adopt the second mode. A corresponding method is also described.

A measuring device includes a measuring unit that measures the morphology of a convex portion, and a position fixing unit that includes an opening in which the convex portion is to be disposed and a fixing member which includes the opening at a center thereof and against which the periphery of the convex portion is to be pressed. The size of the opening of the position fixing unit is capable of being changed.

Methods for the dimensional inspection of a turbomachine component to be inspected are provided. The turbomachine component includes a first surface delimited by a second peripheral surface substantially transverse to the first surface and a profile defined by a numerical theoretical model with a theoretical surface corresponding to the first surface, the first surface having larger dimensions than the second peripheral surface. The method includes determining theoretical points on the theoretical surface of the numerical theoretical model; calibrating calibration points on the first surface of the component to be inspected; calculating an offset axis for each theoretical point with respect to a corresponding calibration point; and acquiring control points on the second peripheral surface of the component to be inspected from the offset axis.

A measurement system includes: measurement target information database that stores measurement point information, including measurement conditions and guidance information for each measurement point, associated with the type of the measurement target; a measuring instrument that performs measurements on the measurement target; an image capturing unit that captures an image of a subject; a display unit; a measurement target identification unit that identifies the type of the measurement target based on the image captured by the image capturing unit; a measurement target information obtaining unit for obtaining the measurement point information corresponding to the type of the measurement target identified by the measurement target identification unit from the measurement target information database; and a setting unit that displays the guidance information included in the measurement point information obtained by the measurement target information obtaining unit on the display unit and sets the measurement conditions on the measuring instrument.

A method includes establishing a first communication connection between a computing device and a coordinate measurement device for submitting, by the computing device, one or more commands to the coordinate measurement device. A second communication connection between the two devices is established for receiving, by the computing device, coordinate data from the coordinate measurement device. In response to receiving, by the computing device, a command for the coordinate measurement device, if the first communication connection is not open, a wait is performed for the first communication connection to re-establish. If the wait is less than a predetermined duration, the method includes re-establishing, by the computing device, one or more channels for the first communication connection.

A mobile dimensioning device, i.e. a mobile dimensioner, is described that uses a dynamic accuracy while still being compatible with the NIST standard. Even if the accuracy division is dynamic and not predetermined, a mobile dimensioning device of the present invention reports the actual dimensioning prior to measurement capture and can therefore be certified and used in commercial transactions.

A measuring system for acquiring measured values by scanning, including an interface for connection to a control unit of a machine. The system is arranged on a movement axis of the machine, and an object can be measured by a measuring instrument of the system. During the measurement of the object, the measuring instrument generates a measured value that is stored in a control unit, that processes and stores the measured value. The control unit has a control module that reads out a position coordinate from the machine via the interface and compares the read-out position coordinate with a specified coordinate target range, and/or compares a time of a timer with a specified point in time, and releases a trigger signal if the control module detects that the position coordinate lies in the coordinate target range and/or if the time has reached or passed the specified point in time.

Various embodiments enable batch inspection of a plurality of workpieces by and inspection instrument such as a coordinate measuring machine. Some embodiments present user interfaces, including graphical user interfaces, to enable an operator to configure a batch inspection system and a batch inspection job, and to monitor and control execution of a batch inspection job.

The following are observed using a camera: a first position of a small hole of a workpiece, which is fixed to a linear-and-tilting-motion stage and rotating with a rotating body, and a second position thereof different from the first position, at a first rotation angle of the rotating body; and the first position and the second position of the small hole of the workpiece at a second rotation angle different from the first rotation angle of the rotating body. A position and a tilt of the small hole are calculated from coordinates of the respective observed positions, and small hole information, which includes the position and the tilt of the small hole, is outputted.
